MLB has been building cases against players with alleged ties to Biogenesis, and Bosch himself recently began cooperating with the sport's investigation. Bosch has turned over documents to the commissioner's office over the past month that confirm his connection to players whose names were listed in company documents, according to ESPN.com.

The length of the suspensions is still at question, according to the report. Previous reports said that baseball was considering 100-game bans for Braun and Rodriguez even though neither player had previously been suspended for a violation of MLB's drug policy.

Braun refused to answer questions about his connection to Bosch during a June 29 meeting with Major League Baseball, according to ESPN.com. Rodriguez is scheduled to speak with MLB investigators on Friday, the New York Daily News and Newsday report.

Before a rehab game with the High-A Tampa Yankees, Rodriguez told reporters he didn't know of a scheduled meeting. He also added that "if I knew, I couldn't share with you guys. We've been fully instructed not to comment on that case, " according to the Daily News.

However, Rodriguez will likely refuse to answer any questions from investigations, according to ESPNNewYork.com. Ten players have already met with MLB investigators and refused to answer questions, according to ESPNNewYork.com.

As his been his policy, Braun said through a team spokesman before the Brewers' home game Tuesday night vs. the Cincinnati Reds that he will not answer reporters' questions about the Biogenesis case. The game marks Braun's first since coming off the disabled list on Monday after missing nearly a month with an injured right thumb.
